I think Ivy flirting with Henry is silly. Ivy seems like more of a villain then she did because she is messing with Ella just for fun. I don’t think she actually cares about Henry. I think the idea that the relationship is with Alice and Drizella seems most likely now.
I still think it is weird that Victoria seems to care about Lucy. She is really her grandmother it seems, in more then name. Ivy thinks that Lucy is now the favorite child in her mother’s life, which does more to suggest that Anastasia was the previous favorite child and that most likely Ivy killed her.
I do think that on one hand we have Alice who knows stuff about Rumpel. She has the chipped cup. She knows who he is. She thinks he was a good man. Then on the other hand, Hook is looking for his daughter and the writers said that Alice is related to multiple people.
I think that it is possible that Rumpel just got confused when he entered the Enchanted Forest 2 and Alice ran into him and Henry went by on his bike. Rumpel thought it was Alice that was supposed to help him, but it was probably Henry. Also, it seemed like Rumpel knew that the curse was going to happen again and made a plan to regain his memories just like he did for the first curse.
It might just be Victoria that did the curse, but i still think it is more likely Alice. It seems like Drizella is more of the villain then either of those characters though, so it might be her even though i think it makes no sense at all for it to be her and for her to still be working for her mother doing things she doesn’t want to do all the time.
Right now Victoria has her memories as does Rumpel. Alice did for a minute but the pills are suppressing it. Lucy does, of course, but we don’t know about Drizella. Everyone else is cursed.
